I tend to avoid using Google services because of their reputation for
data harvesting, which in the past has included WiFi information as part
of Streetview, but perhaps if the SD option fails, then I might try that
next.

No, this doesn't work either.  On the Samsung, the only option presented
by Google's Backup is to back up contacts, I can't see an option to back
up settings.

    Hmmmm!? Strange! On my ancient Samsung Galaxy Tab 4 10.1" (SM-T530)
with Android 5.0.2, i.e. even older than yours, Settings says it can
"Back up application data, Wi-Fi passwords and other settings to Google
servers". (Settings -> 'GENERAL' tab -> 'Backup and reset')

I was going via a different path, which exists on both devices ...
   Settings -> Google -> All services -> Backup and Restore
... which only covers contacts.
On the Samsung Galaxy Tab 2 SM-T719, I don't have your 'General' tab under settings.  Searching its settings for 'backup' gives me ...
   1 Cloud and Accounts -> Backup and Restore -> Backup Settings
     (to Samsung cloud)
   2 Cloud and Accounts -> Backup and Restore -> Backup My Data
     (to Google Drive)
   Cloud and Accounts -> Backup and Restore -> Backup Account
     (create spare account, not relevant here)
   Cloud and Accounts -> Backup and Restore -> Automatic restore
     (auto restore backed up settings when an app is reinstalled)
... also ...
   Developer Options -> Desktop backup password
... of which obviously only the first two are relevant:
1 Is the Samsung backup tested yesterday, seemingly can't be restored to a non-Samsung phone, and anyway seems to have insufficient granularity to restore *ONLY* the WiFi settings, so it would not seem wise to restore this en masse to the Pixel, even if I could find out how.
2 I think this might be the same one as you reach by the path you gave above.  It is a single switch option which was already enabled, and is fully described thus:
"Back up your device data and app data automatically to Google Drive (including WiFi passwords, the Phone log, app settings, and related files.
App data may include personal information such as contacts, messages, and pictures."
If I could find out how to restore only the WiFi settings from that to a different phone, I guess I'd be home and dry, but I can't even find out how to use it to restore to the *SAME* phone that it was made from. Searching Settings for 'restore' gives me only the first and fourth hits above, nothing for restoring any or all of a Google Drive backup.
On the Pixel 8a, searching settings for 'restore' gives me ...
   Google Play Services -> Restore contacts
   Google Play Services -> Google Contacts sync
   1 Apps -> Data Restore Tool
   System -> Erase all data (factory reset)
... of which only the app [1] seems relevant.  Tapping it takes me to its App Info, not the app itself, which says that it's running but not active, and gives details of its permissions. etc.  There is no icon on the home pages for it, and swiping up to get the list of apps gives me nothing of that name or similar, so, how do I run it manually?
Thanks for all your and others' attempts to help, it's a lovely sunny day here in Sutherland, so going for a walk now, back later.
